This resource accompanies our Rethink 2nd Grade Science Matter- Properties & Change unit. It includes ideas for use, ways to support exceptional children, ways to extend learning, digital resources and tools, tips for supporting English Language Learners and students with visual and hearing impairments. There are also ideas for offline learning.

This resource is an activity in which students answer the question, "What happens to the mass of water when it freezes?".

Students will make predictions about the solid and liquid states of matter. They will meet both math and science standards in measurement and physical science.

Students will make predictions about the liquid and solid states of water. They will use both nonstandard and standard units of measurement to compare the weight of water in a container both before and after freezing. (2.P.2.2)

This research task for gifted learners will extend classroom integrated instruction within a science unit on states of matter using close reading of informational texts and creation of a differentiated product. Students will connect the hands-on regular classroom instruction and demonstration of changes of water in a container before and after freezing with the effects of global warming on the melting of the polar ice cap. AIG students will choose from a menu of learning style-based tasks which include technology and collaborative learning experiences. Upon completion, they will give an oral presentation to the class. This lesson was developed by NCDPI as part of the Academically and/or Intellectually Gifted Instructional Resources Project. This lesson plan has been vetted at the state level for standards alignment, AIG focus, and content accuracy.

In this lesson, students explore the properties of water and hypothesize how to cause changes from a solid and gas state to a liquid state. Students use their new science knowledge to have an ice cube melt race.

Students will make predictions about the solid and liquid states of matter. They will meet both math and science standards in measurement and physical science.

This unit was created by the Rethink Education Content Development Team. This course is aligned to the NC Standards for 2nd Grade Science.

In this lesson, students will observe, measure, and describe water as it changes state. Students will work in pairs to use writing and illustrations to record their observations of ice melting to water and water freezing to ice.

In this lesson, students will observe, measure, and describe water, chocolate, and margarine as they change state. Students will make observations about the amounts of these materials before and after freezing and melting.

In this lesson, students will make observations as a popsicle melts. They will also take measurements to compare the weight of the frozen and melted popsicle.

Students will observe and compare water and ice. In Investigation 11, students will discover what happens to volume and weight when water freezes. In Investigation 12, students will discover what happens to volume and weight when ice melts back to water.

In this lesson, students predict what will happen when ice melts in a cup of water. The students observe the ice melting in the water all day, and participate in a class discussion at the end of the day to explain why the water did not overflow. Some vocabulary terms used are volume, displaced, and expand.
